Understanding the relationship between energy balance and obesity is essential to develop effective prevention programs and policies. The International Agency for Research on Cancer convened a Working Group of world-leading experts in December 2015 to review the evidence regarding energy balance and obesity, with a focus on low- and middle-income countries, and to consider the following scientific questions: (i) Are the drivers of the obesity epidemic related only to energy excess and/or do specific foods or nutrients play a major role in this epidemic? (ii) What are the factors that modulate these associations? (iii) Which types of data and/or studies will further improve our understanding? This book provides summaries of the evidence from the literature as well as the Working Group's conclusions and recommendations to tackle the global epidemic of obesity.

A central concept in the evolutionary theory of senescence is the idea that ageing results from life-history trade-offs. In particular, the disposable soma theory suggests that longevity is determined through the setting of longevity assurance mechanisms so as to provide an optimal compromise between investments in somatic maintenance (including stress resistance) and in reproduction. Comparative studies among mammalian species confirm that cells from long-lived species appear to have a greater intrinsic capacity to withstand stresses than cells from short-lived species. Childbearing at older ages has become increasingly common in modern societies because of demographic changes, medical progress and personal choice. While the detrimental effects of late reproduction on infant mortality and genetic diseases have been well documented, little is known about the possible postponed detrimental effects of late parenting.
A nontechnical guide to the basic ideas of modern causal inference, with illustrations from health, the economy, and public policy. Which of two antiviral drugs does the most to save people infected with Ebola virus? Does a daily glass of wine prolong or shorten life? Does winning the lottery make you more or less likely to go bankrupt? How do you identify genes that cause disease? Do unions raise wages? Do some antibiotics have lethal side effects? Does the Earned Income Tax Credit help people enter the workforce? Causal Inference provides a brief and nontechnical introduction to randomized experiments, propensity scores, natural experiments, instrumental variables, sensitivity analysis, and quasi-experimental devices. Ideas are illustrated with examples from medicine, epidemiology, economics and business, the social sciences, and public policy.
This book argues that, paradoxically, at their moment of triumph and fastest growth, cities need nature more than ever. Only if our urban world is full of biophilic cities will the coming urban century truly succeed. Cities are quintessentially human, the perfect forum for interaction, and we are entering what could justly be called the urban century, the fastest period of urban growth in human history. Yet a growing body of scientific literature shows that the constant interaction, the hyper-connectedness, of cities leads to an urban psychological penalty. Nature in cities can be solution to this dilemma, allowing us to have all the benefits of our urban, connected world yet also have that urban home be a place where humanity can thrive. This book presents best practices and case studies from biophilic design, showing how cities around the world are beginning to incorporate nature into their urban fabric. It will be a valuable resource for scholars and professionals working in the area of sustainable cities.
Through the use of careful explanations and examples, Berry shows the reader how to consider whether the assumptions of multiple regression are actually satisfied in a particular research project. Beginning with a brief review of the regression assumptions as they are typically presented in textbooks, Berry moves on to explore in detail the "substantive" meaning of each assumption (such as lack of measurement error, absence of specification error, linearity, homoscedasticity, and lack of autocorrelation). Aimed at improving social science applications of regression, this volume is a must for every student′s and researcher′s library.
Canadian society is rapidly changing. This concise, up-to-date volume masterfully captures this change. Edited by two of Canada's leading demographers, Roderic Beaujot and Don Kerr, this book is an exciting entry in Canadian population studies, drawing from a variety of disciplines, including sociology, geography, economics, history, and epidemiology. The Changing Face of Canada is an essential text for demography courses across the country. Each reading has been meticulously edited and concisely ordered into five essential sections: fertility mortality international migration, domestic migration and population distribution population aging population composition Vital issues include: the role of immigration in Canada's future; the deteriorating economic welfare of immigrants; globalization, undocumented migration, and unwanted refugees; Aboriginal population change; implications of unprecedented low fertility; and the astonishing demographic transformation of Canadian cities.
This is a collection of essays which examine dynamics of change in health care institutions through the lens of contemporary theory and research on collective action. The book conceptualizes the American health care system as being organized around multiple institutions.
